A] In analogy to the procedures described in example 26B] and 26C], [4-cyclopropyl-2-(4-trifluoromethyl-phenyl)-pyrimidin-5-ylmethyl]-methyl-amine (example 130C]) was reacted with 3-(1-ethoxycarbonyl-1-methyl-ethoxy)-5-methoxy-benzoic acid (prepared from 3-hydroxy-5-methoxy-benzaldehyde [Journal of Organic Chemistry (1985), 50(13), 2236–40], by reaction with ethyl-bromoisobutyrate followed by oxidation with sodium chlorite in analogy to the procedures described in examples 52A] and 59A]) to give 2-(3-{[4-cyclopropyl-2-(4-trifluoromethyl-phenyl)-pyrimidin-5-ylmethyl]-methyl-carbamoyl}-5-methoxy-phenoxy)-2-methyl-propionic acid ethyl ester, which was subsequently saponified to yield the title compound as colorless solid.
